T0 @ZZ whom, it may concern:

Be it known that I, WILLIAM N. MARsDEN, a citizen of the United States, residing at Amsterdam, county of Montgomery, and State of New York, have invented certain new and useful Improvements in Glove-Tipping Machines, of which the following` is a specification.

The invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter 1 of a thin metal plate at about the point where described and subsequently claimed.

Reference may be had to the accompanying drawings, and the'reference characters` marked thereon, which form a part of this.

specication.

Similar characters refer to similar parts in the several figures therein.

Figure l is a view in end elevation of a well- I known form of glovesewing machine provided with my novel attachments, the same i being drawn on a larger scale than the other figures. Fig. 2 is a front view' of the trackplate detached. Fig. 3 is a top plan view of the right-hand end of said track-plate. Fig. 4 is a view in front elevation of the feed-plate removed from the machine. Fig. 5 is a view in rear elevation of the same. Fig. 6 is a top plan view of the machine shown in Fig. l. Fig. 7 is a view of the finger portion of a glove-blank, showing the reinforce-tips before the same are folded back and stitched to the fingers. Fig. 8 is a similar view afterthe stitching operation accomplished by the use of my improved attachment. Fig. 9 is a view in front elevation of a broken-away portion of the feed-plate and clamps, showing several finger portions of a glove supported thereupon as the same would appear just after the stitching operation and before the chains of stitching connecting the neighboring fingers have been cut. Fig. l0 is a vertical cross-section of the same, taken on the broken line l0 l() in Fig. 9, showing a finger portion of a glove before the insertion of the stitching.

In the manufacture of certain kinds of gloves it is customary to reinforce the ends of certain of the fingers where most exposed to wear. This is commonly accomplished by making the finger at the point where it is desired to reinforce the saine of double thickness of fabric by applying and securing thereto a reinforce piece or tip, which for convenience is made integral with the finger-strip itself and folded back thereupon, the end of the folded-over tip being stitched to the body operation to the formation of the fingershcaths.l

As a desirable mode of procedure to accomplish the stitching of the folded-over fingertips to the finger-bodies the finger portions of the glove-blank may be folded over the edge the stitching is to be inserted, with the tips folded back upon the finger-bodies, the edge of the tip being exposed adjacent to the foldline of the finger-body just above the edge of v said plate, in which position the parts are held by spring-,clamps while the blank thus.

mounted upon said plate is fed to a sewingmachine which performs the stitching operation.

My invention relates in certain of its fea- I tures to' sewing-machine attachments for thus supporting and feeding to the machine such glove-blanks and in certain other features to attachments for separating and re- A' v leasing the glove-blanks at the conclusion of such stitching operation.

The principal object of the invention is to relieve the operator from much of the work attendant upon the preparation ofthe blanks for their presentation to the sewing mechanism and the subsequent releasing and separating of the blanks.

Other objects of the invention will appear in connection with the following description.

Referring to the drawings, wherein the invention is shown in its preferred form, I have shown my attachment applied to a wellknown type of glove-sewing machine wherein the work is adapted to be fed between a pair of disks l and 2, the former being rotatively mounted upon the upper end of a movable arm 3 and the latter being fixed upon a spindle 4, rotatively mounted in a bracket 5, fixedvupon the body or frame 6 of the ma- IOO chine, which spindle has fixed thereon a ratchet 7, adapted to be given a step-by-step rotative movement by means of the pawlS, which is operatively connected with the driving mechanism of the machine in the usual adjacent to their point of contact with each n other in position for the needle to play through the exposed edge of the goods clamped between and fed by the said disks.

' The construction of a machine of this type being well understood in the' art, further description of the same will be unnecessary.

In carrying outJ my invention I mount in fixed position by means of screws -11 uponA the bed of said machinein a vertical plane 'extending about midway between the-disks 1 and 2 and at right angles to the needle a trackplate 12, having formed thereon byaseries of grooved rollers 13 a track or way for the feedvplate 14, the base of which is adapted to freely nt the grooves in said rollers, the feedplate being adapted to rest upon said rollers in an upright position with its upper edge between the disks land 2.

A step-by-step positive feed movement is 4imparted to said feed-plate through a gearfolded-over portions of the finger-bodies to p accomplish the stitching of the edge of the tip to the finger-body as saidwplate is fed i through the machine.

As a means for holding the 'linger-tips in their proper relation to the folded-over portion of the respective finger-bodies I have shown the feed-plate provided on itsv front side with a separate spring-clamp 17 for each finger to be tipped, said clamps beingattached to said plate at their lower ends by means of screws 18 and being of bowed form with their upper ends adapted to engage and press firmly against the front side of the feed-plate, the folded-over portion of the glove-finger, and its reinforcing-tip, as shown in Fig. 10. l.

I have shown the feed-plate thus provided with twelve clamps 17, adapting the plate to simultaneously hold all of the parts of apair of gloves to be thus provided with the reinforcing members.

The little fingers of the gloves are not ordinarily reinforced. l p

Certain of the clamps are -considerably wider than the others, as the clamps 17 u for the index-fingers, which are ordinarily cut of double Width, and 17h, which represents the clamps for the thumbs, cut separately from the other parts of the glove.

The clamps 17 are adapted to be all simultaneously opened by means of a shaft or plate 19, eccentrically mounted in bearings upon the front of the feed-plate and adapted to be operated by an offset arm 20. By rocking said shaft or plate 19 by means of the arm 20 the upper ends of the clamps are forced away from the feed-plate to permit the insertion of the goods between the plate and clamps, which insertion is accomplished by hand by the operator.

I have shown each clamp 17 provided with a separate automatically-operated catch for holding the same in open position, the same comprising a lever 21,pivoted upon the clamp at 22, and adapted in one position to pass freely througha slot 23 in the feed-plate. The lever is so overbalanced at its inner end that it normally assumes a position so deof the sticthing operation to simultaneously free the clamped members by means of the cam-plate 19 and at the same time to lock said clamps in open position by means of the automatic action of the levers 21 whereby the clamps are all held open independently of each other when the cam-plate 19 is restored to its normalposition. This permits of quick removal of the work from the plate. In applying the work to the plate, however, y each finger or thumb portion with its reinforcing-tip must be adjusted separately by the operator, and as soon as adjusted it can be clamped in position by its appropriate clamp, which isrendered effective for this purpose by a rocking movement im arted to the catch 21 by the operator to ring the same into lin'e with its slot 23. When the finger portions have been thus clamped in position, the body portion of the glove is drawn over the edge of the feed-plateinto engagement with a' row of pins 24.- on the back side of said. plate, which hold the finger portions of the glove stretched over the edge of the feed-plate, in which position the dependent body portions of the glove are confined between the back side of the feed-plate and a shield 25 mounted thereon, adapted to protect the glove from becoming entangled or soiled by contact with the gears or other feeding mechanism.

As a means vfor automatically opening all the clamps upon the completion of the stitching operation I have shown mounted upon the track-plate 12 an inclined block 26 in the path of and adapted to engage the offset arm 2() and automatically operate through the same the cam-plate 19 immediately after-the last feed-plate-sup orted member of the work has been stitc ed, the feed-plate being thus delivered from the machine atthe end of its movement therethrough, with'the clamps open to permit the immediate removal of the work bythe operator.

IOO

As the stitching operation is continuous during the passage of the feed-plate through the machine, the neighboring finger portions are upon leaving the needle connected by a chain of stitching C, which bridges the interval between the neighboring finger portions, which chain must be broken or cut subsequently to the stitching operation. The cutting of said chains of stitching may be accomplished by hand or in any known manner. I have shown means whereby the same can be accomplished automatically during the progress of the passage of the feed-plate through the machine. In carrying out this feature of my invention I mount a sharplypointed knife 27 upon a knife-bar 28, reciprocatory in a slideway 29, pivotally mounted at 30 upon the frame of the machine, through which slideway the knife-bar is adapted to be reciprocated by means of an arm 31, projecting upwardly from a slide-bar 32, reciprocatory in fixed slideways 33 and 34, said slidebar being adapted to be automatically operated in a direction to accomplish a forward movement of the knife by means of a coilspring 35, interposed between one of said slideways 34 and a collar 36, fixed upon said slide-bar.

The slide-bar is adapted to be operated in the opposite direction by the engagement of the follower 37, mounted upon its end, with a plate 38 fixed upon the back of the feedplate, successive cam-like portions of which act upon said slide-bar in opposition to the spring 35.

In addition to the reciprocating motion in a horizontal line thus imparted to the knife an up-and-down reciprocating motion is nimparted thereto by oscillating the slideway 29 upon the pivot 30, which is accomplished by means of a slide-bar 39, vertically arranged in fixed slideways 40 and 4l, having its upper end pivotally connected at 42 with the oscillating end of said knife-slideway 29 and having an arm 43 offset from its lower end and provided with a follower 44, engageable with a cam-like projection on the plate 45, fixed upon the back of the feed-plate and serving at certain times to lift said arm, slide-bar, and knife-slideway 29 against the force of the coil-spring 46, interposed between the slideway 40 and a collar 47, fixed upon said slidebar.

The cam-like projections on the two plates 38 and 45 form gradually-inclined risers terminating abruptly at their highest points, and they are so arranged and proportioned that as each interval between neighboring fingers on the glove carried by the feed-plate is brought opposite the knife the follower 44 passes off from the tip of one of said projections to the bottom of the next incline or projection, causing a quick descending movement of the knife to its lowermost position, immediately after which the follower 37 passes from the highest point of one of saidl projections and is forced by the spring 35 to the bottom of the next incline or projection, causing a quick forward movement of the knife, whereby its point is forced beneath the chain of stitching connecting said two fingers. Thereafter as the two followers 44 and 37 ride up the respective inclines on the next succeeding projections the knife is raised so as to sever said chain and is then gradually drawn back in preparation for the next succeeding forward stroke.

By the use of my invention it is necessary for the operator only to apply the goods to the feed-plate and insert the same in the machine. The knife is provided with an overhanging shield 48 for the protection of the operator. By employing a plurality of such feed-plates the operator can be filling one feed-plate with the goods while a previouslyfilled plate is passing through the machine, so that a material saving in time and labor is accomplished. j

In the drawings, 46 represents the fingerbodies, 47 the reinforce-tips, and 48 the stitching connecting the edge of the tip with the finger-body.

1. In a machine of the class described, the combination with the stitch-forming mechanism; of a work-supporting feed-plate, a plurality of work-,clamps mounted upon said feed-plate 5 means for feeding said plate past the stitch-forming mechanism; and a clampopening member engageable with all of said clamps simultaneously.
